Ac_K 560ccbeb2d Refactoring commands handling (#728)
* Refactoring commands handling

- Use Reflection to handle commands ID.
- Add all symbols (from SwIPC so not all time accurate).
- Re-sort some services commands methods.
- Some cleanup.
- Keep some empty constructor for consistency.

* Fix order in IProfile
